実験手順

The 7,8-dimethoxy-(10,11-dihydro-5H-pyrrolo[2,1-c][1,4]benzodiazepin-10-yl)-(4-bromo-3-methyl-phenyl)-methanone of Step C (1.0 g) was reacted with 2-trifluoromethylphenyl boronic acid (0.645 g, 1.5 equiv.), potassium phosphate (0.964 g, 2.0 equiv.) and a catalytic amount (0.050 g) of tetrakis(triphenylphosphine) palladium(0) in refluxing dioxane (10 mL) under nitrogen for 24 hours. The reaction was then cooled to room temperature, filtered through Celite, and the solvent removed in vacuo. The residue was dissolved in dichloromethane and the solution was washed with water, dried over anhydrous magnesium sulfate, filtered and evaporated to dryness. The crude product so obtained was purified by chromatography on silica gel eluting with 5% ethyl acetate/dichloromethane to provide the title product (1.0 g) as a white crystalline solid, m.p. 187–188° C.
